Despite being home to some of the world 's poorest nations , Africa has a vibrant cell phone market , considered by industry analysts as among the fastest-growing worldwide .

Administration officials said they set up different numbers across the continent for citizens to communicate with Obama , whose father was from the east African nation of Kenya .

`` Over the past week , we have been collecting questions , comments and words of welcome for President Obama via SMS , Twitter , Facebook and from newspapers across Africa , '' the White House said on its Web site .

Three journalists from South Africa , Senegal and Kenya will vet the questions and provide a few to Obama , who will address them on African radio stations and via a Web video Monday , the White House said .

Peter Kimani , a senior associate editor for a Kenyan daily , The Standard , is one of the three .

`` The U.S. Embassy picked and vetted the journalists , and we are getting the questions , then it is up to us to determine what questions we will forward to the president , '' Kimani said . `` It is our judgment call on what to pick . ''
